spring - 将 JAXBContext 注入(inject) spring

Question

我正在尝试将 JAXBContext 注入(inject) Spring 应用程序上下文，通过:

<bean id="jaxbContext" class="javax.xml.bind.JAXBContext" factory-method="newInstance">
  <constructor-arg type="java.lang.Class" value="com.package.MyClassName"/>
</bean>

抛出异常:

No matching factory method found: factory method 'newInstance'

我也试试:

<bean id="jaxbContext" class="javax.xml.bind.JAXBContext" factory-method="newInstance">
  <constructor-arg type="java.lang.String" value="com.package"/>
</bean>

它会抛出一个异常:

javax.xml.bind.JAXBException: "com.package" doesnt contain ObjectFactory.class or jaxb.index I did put a jaxb.index file inside the package "com.package" and has a single line "MyClassName" in the file.

Answer 1

@Tomasz 的答案是我推荐的解决方案，但如果您想坚持使用 JAXBContext，那么您的第一个示例失败的原因是 static getInstance() method on JAXBContext不采用单个 Class 参数，它采用它们的可变参数列表。所以你需要注入(inject)一个列表，而不是一个类:

<bean id="jaxbContext" class="javax.xml.bind.JAXBContext" factory-method="newInstance">
  <constructor-arg value-type="java.lang.Class">
    <list>
       <value>com.package.MyClassName</value>
    </list>
  </constructor-arg>
</bean>
